Actual Perft results from SMIRF

Archived from groups: rec.games.chess.computer (More info?)

More than a year ago I have posted Smirf's early Perft results for the standard
8x8 chess opening position. Smirf today is able to play Chess960 and several
10x8 chess variants based on Capablancas extended piece set. To those, who are
interested in performance tests results here are Smirf's actual values coming
from a system with Win-XP Pro, Intel P4, 2.8 GHz:
